Where is the 1995 Buick Riviera crankshaft pos.sensor located?

The 1995 Buick Riviera crankshaft position sensor (CKP sensor) is located on the passenger side of the engine block, near the crankshaft pulley. It's usually mounted within relatively easy reach, but the exact placement might vary slightly depending on specific engine variations. You'll likely need to consult a repair manual specific to a 1995 Buick Riviera with the engine type (e.g., 3.8L Supercharged) to get the precise location and access instructions. A picture from such a manual would be the most helpful.
